The mismatched filter bank is obtained by minimizing a weighted maximum of the PSL and PCCL on the basis of the convex optimization. Compared with the iteratively reweighted least squares (IRLS) method, the proposed convex method can get the optimal mismatched filter bank with the minimum PSL and PCCL, and can also control the system signal-to-noise ratio loss (SNRL). Numerical examples show that the optimal mismatched filter bank at the cost of a slight SNRL can achieve a good improvement of the PSL and a moderate improvement of the PCCL, if the filter length P and the weighting factor w between the PSL and PCCL are appropriately chosen.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126178216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the techniques for signal detection, the energy detector (ED) is widely used due to its simplicity. However, setting the threshold for the energy detector requires some knowledge of the noise power level, which can be provided by suitable estimation methods. In this paper, we derive analytical expressions relating the threshold, the received signal-to-noise ratio (SNR), the probability of detection (PD) and the probability of false alarm (PFA), assuming a practical noise power estimator. The analysis can be used to design EDs that fulfill spectrum sensing requirements in cognitive radio (CR) scenarios.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126220310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A HMPAR comprises a large number, MP, of T/R elements, organized into M subarrays of P elements each. Within each subarray, passive elementlevel phase shifting is used to steer transmit and receive beams in some desired fashion. Each of the M subarrays are in turn driven by independently amplified phase-coded signals. This paper proposes new transmit signal selection strategies based on the observation that some MIMO signal sets, such as those proposed by us previously, cause a very rapid sequential or raster scan across some field of view. Exploiting this property allows one to create and process multiple beams simultaneously. Furthermore, there exists a range-angle coupling in the transmit and receive signals that may lead to high-resolution target localization.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115544076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When each node is equipped with a single antenna, the relay-destination link will become the bottleneck that limits the overall network diversity gain. In this paper, we propose the use of multiple antennas at the destination node to enable the network diversity gain and consequently improve the overall outage performance. Analysis of the outage probability is presented to provide insightful understanding of the performance for three different protocols with the use of different numbers of destination antennas. Numerical results confirm the analytical results and demonstrate the effectiveness of the proposed cooperative network schemes.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130508461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are particular difficulties associated with the airborne case such as the limited antenna aperture, high platform velocity and severe clutter levels which present difficult waveform design challenges. This tutorial will consider the design parameters of high pulse repetition frequency (PRF) and medium PRF waveforms commonly used in airborne pulse Doppler radar modes. The majority of this tutorial will be devoted to the issues concerning the selection of the number of PRFs and of the PRF values used in the medium PRF mode. PRF optimisation methods using evolutionary algorithms used by the author and his colleagues in a number of recent studies will be described. Examples will be given of airborne fire control radars, airborne early warning systems and active radar seekers used in anti-aircraft missiles.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126082507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These approaches are particularly important for scenarios where the noise environment can change and therefore affect the amount of resources necessary for detection and estimation. A common way to manage these tradeoffs uses a min-max estimation strategy to handle the worst case signal and noise distribution and set resources and detection thresholds accordingly. In many of these approaches however, the difficulty of setting the number of resources to achieve the min-max bound for the worst case probability are difficult to gauge. We propose an approach that considers resource allocation as a problem in sparse approximation. The idea is to measure the current probability distribution and adapt to stay within the worst case bound while using the minimum number of resources necessary.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124170586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
